Biggest Upsets

How often does the bigger school actually win, and which underdogs threw the form book out entirely? The most improbable results in the database, with the ELO swing each one caused.

An upset only means something if you know what was supposed to happen. So before the highlight reel, a baseline: when a bigger-classification school plays a smaller one (staying inside the same division, because Division I and Division II don't play by the same rules), how often does size actually win out?

Bigger helps, but it is no guarantee. The largest public schools (3A) beat the smallest (1A) about 72% of the time, which means the little school still wins better than one game in four. The clearest size advantage in the state is in Division II, where the AA privates beat the A privates roughly three times in four. Everything below is what happens when that baseline breaks.

Win probabilities from pre-game ELO in the Tennessee Soccer Stats game log; classifications from our school registry (current cycle, used as the size tier); state-tournament results from the TSSAA bracket. Featured upsets are limited to one- to three-goal results, since a heavy-margin "upset" usually reflects a stale rating rather than a true shock.

ELO win probability is computed from the two teams' ratings entering the game; classifications are the current-cycle tier and may differ from a team's class in older seasons. Division I and Division II are never compared by classification.
